Description
Technical field
The present invention relates to garbage classification field, in particular to a kind of garbage classification two-dimensional code generation method.
Background technique
In recent years, with the fast development of global economy and increasing sharply for the size of population, city size constantly expands therewith
Greatly, domestic waste quantity is caused to steeply rise, domestic waste problem is positive worsening for a global crisis.
The problems such as land erosion that " garbage-surrounded city " is caused, environmental pollution, the health of the public is not only seriously threatened, but also have become
Influence and restrict one of China or even the factor of countries in the world urban sustainable development.Crack that " garbage-surrounded city " is tired, primary
It is the realization Reducing Municipal Solid Waste from source, completes garbage as resource, harmless treatment, therefore push house refuse point
Class has become the task of top priority and inexorable trend.
City garbage specification is relatively slow in China's implementation, traces it to its cause and essentially consists in, the garbage classification code on refuse bag
Lack confidentiality or be difficult to understand and know to classify, the citizen of shortage is compared for garbage classification knowledge, many rubbish are answered
Which kind of this is attributed to and is unaware of, and throws out without care with will being formed with conscious & subconscious in this way, and classification is made to perform practically no function；Simultaneously for
The privacy whether identity information of refuse bag can reveal user is still suspected, and worries that personal information can expose also to a certain degree
On hit people to the enthusiasm of garbage classification.In the case, propose that a kind of simple possible, safety are not easy the colored rubbish cracked
Rubbish classification two-dimensional code generation method, generates the colored garbage classification two dimensional code with " uniqueness and safety ", with effective
Protection privacy of user instructs garbage classification, imperative.
Summary of the invention
Goal of the invention: the purpose of the present invention is to solve deficiencies in the prior art, provide a kind of colored garbage classification
The generation method of two dimensional code utilizes the change in location scramble rule of chaotic signal sequence front and back using 3 kinds of customized corresponding relationships
Scramble is carried out to the ciphertext numerical value in 3 customized numeric type datas and ciphertext numerical value mapping table respectively, while being directed to body
The different numerical value of part Hidden Codes change data carry out corresponding positive, reverse diffusion respectively and encrypt, further according to the correspondence after scramble
Relation table generates the concealed encrypted code of identity, and then combination producing garbage classification code, while obtaining colored garbage classification two dimensional code,
Guarantee proposed method simple possible with this, there is very strong safety, be not easy to crack, the colored garbage classification two dimensional code tool of generation
There is " uniqueness, safety and garbage classification guided bone ".
